Abstract

The invention discloses a ring network multicast service realization method, system and device. The method includes: configuring a multicast ring network mode on each node device in the Ethernet ring network, and after configuring the multicast ring network mode, the node device The blocking port can forward the IGMP join message and cannot forward the multicast data message; and the port on the node device in the Ethernet ring network is configured as a multicast cascading port and a static routing port; when the node device receives the IGMP When adding a message, add the port that received the IGMP join message as a member port in the multicast forwarding table of the requested multicast group, and forward it to other ports in the Ethernet ring network according to the set forwarding rules The IGMP join message. In the event of a failure, it is possible to quickly switch over.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a ring network multicast service realization method, system and device. Background technique [0002] With the development of Ethernet technology, Ethernet technology has been widely used in enterprise networks, carrier metro networks and access networks. Especially with the development of Internet TV (Interactive Personality TV, IPTV), higher requirements are put forward for enhancing the reliability of the Ethernet itself, network fault convergence time, and user experience. [0003] The traditional multi-level direct network needs to replicate the multicast stream on each downlink port of the multicast branch node, while the Ethernet ring network only needs to replicate once on the entire ring network. Therefore, the Ethernet ring network is Multicast applications such as IPTV have advantages over traditional multi-level direct-connected networks, which can greatly improve t...
